| 目的评价单髁置换术治疗膝关节内侧间室骨关节炎的临床疗效，探讨其手术适应证、手术技术及假体选择。方法回顾性分析行单髁置换术治疗膝关节内侧间室骨关节炎的43例患者的临床资料，根据术中选用的单髁假体不同分为Oxford假体组（17例，18膝）和Zuk假体组（26例，27膝），观察比较两组患者手术前后美国膝关节协会评分（KSS）、术后并发症发生情况及对手术疗效的主观满意度。结果患者术后随访18～46个月。手术前后两组患者KSS评分比较均无统计学差异（均P＞0.05）；组内比较，两组患者术后KSS评分均高于术前（均P＜0.05）。两组患者在随访期间均无假体松动、下沉等并发症发生，且对手术疗效的主观满意度均较高。结论单髁置换术治疗膝关节内侧间室骨关节炎近期临床疗效满意。Oxford和Zuk假体近期临床结果相当，手术创伤小，并发症少，患者易接受。 |

| Abstract: |
| Objective To evaluate the clinical effect of unicondylar knee arthroplasty in the treatment of medial compartment osteoarthritis of knee. Methods The clinical data of 43 patients with medial compartment osteoarthritis of knee treated with unicondylar knee arthroplasty were retrospectively reviewed. According to the prostheses used in the operation, patients were divided into Oxford prosthesis group (17 cases, 18 knees) and Zuk prosthesis group (26 cases, 27 knees). The American Knee Society score (KSS), the incidence of postoperative complications and the efficacy of the subjective satisfaction were observed and compared before and after the operation in two groups. Results Patients were followed-up for 18 to 46 months. There were no significant differences in KSS scores (P ＞0.05) before and after operation between two groups. The postoperative KSS scores were higher than those before operation in both groups (P＜0.05). There were no loosening or subsidence
of the prostheses and other complications during the follow-up period in two groups. The subjective satisfaction of patients with the efficacy of surgery was higher in both groups. Conclusion The clinical curative effect of Oxford and Zuk prostheses is satis- factory with less surgical trauma, few complications and higher acceptability of patients in treatment of medial compartment os- teoarthritis of knee joint. |
